For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with the resonant frequency of atoms, a method so accurate that it serves as the ...

Adelaide University researchers have successfully tested a new type of portable atomic clock at sea for the first time, using ...

This breakthrough in precision timing is about the size of your fingernail and only loses one second every 30,000 years. Reading time 2 minutes This tiny cube fits on the tip of your finger and also ...

China’s state aerospace conglomerate has begun batch-producing a rubidium atomic clock compact enough to fit roughly in the palm of a hand, a step that could sharpen the country’s satellite navigation ...

Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world measures one second in the near future. Researchers from Adelaide University ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.
